The object of this invention is to furnish an improved machine fornailing together the parts of round boxes, which shall be convenient inuse and effective in operation, enabling the boxes tobe nailed quicklyand accurately.

The invention consists in the combination of the grooved eccentricwheels and the pins with the gear-wheels and the sliding punchholders;in the combination of the flange and its adjustable gib and theadjustable angleplate with the sliding punch-holders and the bed-plateof the machine; in the combination of the pairs of flanges and theiradjustable gibs and the slide-blocks with the bed-plate of the machine;in the combination of the swiveled screws, the gear-wheels, and thecrank-shaft with the slide-block and the bed-plate of the machine; inthe combination of the pivoted die-holders and the dies and theirsprings with the slide-blocks; in the combination of the spring with thedie-holder and the slide-block; and in the combination of thespring-catch and the pin with the slide-block, the die-holder, the dies,and their springs, as hereinafter fully described.

A is the frame of the machine, to the top of which is attached acircular bed-plate, B. Upon the upper side of the bed-plate B are formedsix, more or less, pairs of parallel flanges, 0, between which areplaced the slide-blocks D,

which are keptin place and are centered by gibs I E, interposed betweenthem and the flanges U. The gibs E are kept in place and are set upagainst the slide hlocks D by set-screws e, passing in through the saidflanges O. In the lower part of the blocks D is formed a screwhole,through which passes a screw, F. The screws F are swiveled to the plateB, and to their inner ends are attached bevel-gear wheels G, the lowerparts of which project into a ringgroove formed around the center of theplate B, and into the teeth of which mesh the teeth of the largebevel-gear wheel H, which is pivoted to the upper end of a hub formed inthe center of the plate B, so that all the screws F may be turned at thesame time and in the same direction. The gear wheels G H are turned byasmall bevel-gear wheel, I, the teeth of which mesh into the teeth of twoof the gear-wheels G, between which it is placed. The gear-wheel I isattached to the inner end of the shaft J, which works in bearingsattached to the plate B, and to its outer end is attached the crank K,so that by turning the said crank K in one or the other direction theslide-blocks'D may be moved in or out, as desired. L is the die-holder,upon the upper side of the inner end of which are formed lugs, toreceive the bolt by which the said die-holder is pivoted to the block D.The die-holders L, when left free, are raised into, and held in, anerect position by the springs M, attached to the pivoting-bolts of saiddie-holders L. N are the dies, which are placed within the cavity of theholders L, and the backs of which are recessed to receive the springs O,by which they are held together. To one of the dies N is attached a pin,P, which passes out through a hole in the side of the holder L, so thatwhen the dies N are forced apart by the insertion of a nail between themthe said pin P may project, to catch upon the spring Q when thedie-holder L is lowered into a horizontal position, and may hold it inthat position until the said pin is drawn inward by the dies beingallowed to move toward each other. The nails are forced through. thedies N and into the box by the punches B, the outer ends of which arescrewed into the upright arms of the punch-holders S, and are secured inplace adjustably by nuts 1, screwed upon their outer ends.

The horizontal arms of the punch-holders S are placed in radial positiondirectly beneath the ways for the slide-blocks D, with one side restingagainst a flange, '1, formed upon the lower side of said plate B. Thepunch-holders S are secured in place by angle-plates U, bolted againstthe plate B, and which rest against the side and bottom of the saidholder S. The bolt-holes in the angle-plates U are elongated, so thatthe said angle-plates may be adjusted to center the punch-holders S, andto take up the wear. V are gibs interposed between the punch-holders Sand the flanges T, and held in place adjustably by set-screws t, passingin through said flanges T, and which, in connection with the angle-plateU, enable the wear to be taken up, and" the punch-holder and punch to beaccurately centered.

To the lower side of the horizontal arm of the punch-holder S isattached a pin, W, which projects downward through a slot in the lowerpart of the angle-plate U, and enters a ring-groove in the upper side ofthe wheel X, attached ecceutrically to the gear-wheel Y.

All the gear-wheels Y are pivoted to aring plate or frame, Z, attachedto the frame A near its upper end, and the teeth of all of said Wheelsmesh into the teeth of a single central wheel, A, attached to the shaftB.

The upper end of the vertical shaft B revolves in the lower end of thehub in the center of the plate B, and its lower end revolves in a socketor step formed in or attached to the cross-bar ot' the frame A. To thelower part of the shaft B is attached a bevel-gear wheel, O',into theteeth of which mesh the teeth of the gear-wheel D, attached to thehorizontal shaft E. The shaft E revolves in bearings attached to theframe A, and is driven by any convenient power.

In using the machine the bottom of the box is placed upon the center ofthe plate B, and the sides or hoop of the box is placed upon the flangesG around the edge of the said bottom. The crankK is then turned to bringall the slide-blocks D inward to rest against the hoop of the box, andpress it against the edge of the said bottom. The shaft B is then turneduntil the punch-holders S have reached the limit of their forwardmovement, and the punches R are then adjusted so that their forward endsmay strike the hoop of the box. The punches R are then drawn back, nailsare inserted in the dies N, the die-holders L are turned down into ahorizontal position, and the punch-driving mechanism is thrown intogear, which carries the punches R forward, and forces the nails into thebox. As the punches are withdrawn their driving mechanism is thrown outof gear, and the dieholders L rise into a vertical position, so thatanother set of nails can be readily placed in their dies N. In this wayround boxes can be quickly and accurately nailed, the punches requiringto be adjusted only when boxes of a difierent diameter are to be nailed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination of the grooved eccentric wheel Xand the pins W with the gear-wheels Y A andthe sliding punch-holders S,substantially as herein shown and described.

2. The combination of the flange T and its adjustable gib V, and theadjustable angleplate U, with the sliding punch-holder S and the plateB, substantially as herein shown and described.

3. The combination of the flanges O and their gibs E, and theslide-blocks D, with the plate B, substantially as herein shown anddescribed.

4. The combination of the swiveled screws F, the gear-wheels G H I, andthe crank-shaft J with the slide-blocks D and the plate B, substantiallyas herein shown and described.

5. The combination of the pivoted die-holders L, and the diesN and theirsprings O, with the slide-blocks D, substantially as herein shown anddescribed.

6. The combination of the spring M with the die-holder L and theslide-block D, substantially as herein shown and described.

7. The combination of the spring-catch Q and the pin P with theslide-block D, the dieholder L, the dies N, and their springs 0,substantially as herein shown and described.
